If you’re looking for a simple way to organize your notes and thoughts, take a leaf out of the social media playbook with this app, and just add a hashtag. This note-taking app also lets you “mention” important people or places in your life with the @ symbol as an alternate method for organizing. Notes are easy to add and easy to manage since you can delete them with just a swipe. It would be nice to be able to reorganize your notes, but with the easy filing system, it shouldn’t take you too long to find what you’re looking for. Free, for Android devices.
